I already (Dec. 25, 2011) filed an issue http://youtrack.jetbrains.net/issue/AS-204 that (Astella EAP) "Make" is not working - i.e. the project is built everytime regardless of changes to the source code. This bug makes Astella completely unproductive for production development, so I refuse to evaluate it further. Now this Make bug has been carried over from Astella to IDEA 11.1 EAP. Ahhhhhhhrrrrrrrrggggggg.
Please also fix http://youtrack.jetbrains.net/issue/AS-248. Debugging Flex 3 projects with Flash Player 11 is also broken http://youtrack.jetbrains.net/issue/IDEA-80407.
Why do you work on useless (Astella) features like Flex UI designer (which nobody needs, has been dumped from future Flash Builder releases) when there are bugs that make productive work impossible?
I think the new UI for Flex modules is horrible, IDEA 11 was perfect.
